Christmas Defense is a game where players take on the role of a defender tasked with protecting a holiday-themed tower from waves of incoming enemies.
The player's primary interaction is with a small number of defensive towers, which can be upgraded and placed strategically around the map to take out enemy units.
The objective is to survive as long as possible, fending off increasingly difficult waves of enemies. The game runs in the browser without the need for a download or registration, allowing players to jump in and start defending their tower right away. By strategically placing and upgrading their towers, players can slow the enemy advance and push back against the hordes. As the game progresses, the challenge will only increase, requiring players to think critically about their tower placements and upgrade choices.
